Background and objectives Survival rates in patients transfused in 1993 and 2000 were compared in relation to diagnoses and surgical interventions. Materials and methods Blood centre and hospital records of all patients transfused from March to May in Örebro County in 1993 ( n = 932) and 2000 ( n = 990), were matched with the national register of deaths. Results Relative risk of death within 1 year, adjusted for diagnoses, operations and other confounders in patients transfused in 2000 compared to 1993 was 0·78 (CI 0·66–0·91). Among those transfused 1993, 39% were alive after 7 years. Conclusion The improved survival among those transfused in 2000 could not be accounted for by differences in ages or case‐mix.
